Can they put two Fully discrete, Fully balanced and Differential amp modules in one chassis ?

Can they put two XPA-1 's in one Chassis ?

This is not a trick question.  |

You can do fully balanced differential preamp in a single chassis.

Seems I remember reading that was in the works but until then the XPA 1's would remain in the line up.

Would you need two power cords ?

I thought Emotiva already did that....?  |

It is an Emotiva Amp from years back. However, I don't think is differential balanced.

I have seen high dollar amps with two power supplies in one chassis long ago and looking for one now just does not cut it with the performance you can get from modern amps of good value. It cost to make an amp like the XPA-1 now. Nick will tell you that he has the stuff with the XPR-1's he has. Even they are more than you need at a great price. I just want to know if you think Emotiva can put two XPA-1's in one chassis. They could charge a premium for it, but having the same performance without needing two units and all the weight would be killer. |

That gentlemen is an RPA. They were dual mono NOT of balanced design but a very fine amp. 200 wpc class H I am going to change my Thread name to Dual Balanced Differential Mono. Problem is the XPA-1 if you look at it has TWO amp modules on either side. This is what makes it balanced.  Also the power supply is huge. And there are large capacitors in there. There are also thick heat sinks.  All this basically means the XPA-1 has a lot of amp in the space it occupies. Not to mention it has to vent off large amounts of heat in class A. So let's say you have to XPA-1s in one chassis you need to accommodate FOUR amp blades, two very big power supplies, and twice the amount of heat. And twice the amount of heat is not easy to manage. So the XPR-1 is an example of what it takes to make twice of everything.  You see how much more space the capictance and the 3.2 KVA transformer takes up. Now if you were to get with dual monoblocks, the power supplies will take up even more space due to the circular nature of both of them. It will be a very big very heavy amp. Now...I think a more realistic thing would be fully balanced dual modolues powered by a single XPA gen 3 switching power supply with none of hte class A stuff. So you lose the monoblocks, the class A, and the massive torroidal power supply (and also likely quite a bit of capacitance). But you do get to have fully balanced modules. |

This: "Now...I think a more realistic thing would be fully balanced dual modolues powered by a single XPA gen 3 switching power supply with none of hte class A stuff." Garbulky I know that the vast horsepower that both the XPA-1 and XPR-1 single blocks put out are there calling card. I also know although there are a few reports on the Gen 3 and there switching power supply, I think we are going to find you do not need those huge power supplies and huge banks of capacitors. Lonnie is making big dual modules to go in the new Gen 3 chassis. 500 or 600 watts, who knows yet. Mono or Stereo, who knows ? Could one of these dual or single modules be Fully Balanced Differential ? A mono channel. Two of them in the same chassis and sharing or not sharing that new switching power supply. If you had to use two separate new switching power supplies in that same chassis to make it work and give it the horsepower you want ? Can you do it with one power cord ? A 45 or 50 lbs. single chassis with two Fully Balanced Differential channels. No class A required. |

I don't see anything technically stopping someone from putting two, fully balanced monoblocks in one case. But, it seems to defeat a key purpose on monoblocks... That being, monoblocks can be placed close to the speaker minimizing speaker cable lengths AND looking awesome/intimidating sitting on a little stand (or in my case, hanging on the wall!) near the speaker.
In one case, that's not going to happen!

I'll take a xpr-1 pair! Haha
Though the idea of a dual mono in one chassis is very nice! And would help me and others out with limited space.
I have 2 spots for large amps and one could be a dual mono and the other a multi channel amp for ht.

Mark Currently I'm vertically bi-amping with a pair of XPA-2s. It would be nice if the channels in each amp were fully balanced. That way I could take advantage of the fully balanced DAC in my XMC-1. A Gen 3 amp with dual balanced blades would certainly be just the ticket. |
